Great Upper/Great Buying Experience


I read many great reviews on the Spike's upper and after receiving it, I understand why! Very impressed with the quality and fit and finish. Great price and super fast delivery from Primary Arms. Will definitely shop here often!



I went originally went threw Spikes Tactical to get my upper receiver and after I found out that they were on back order and would take 6 months due to the elections. I couldnt wait for it. So I searched around and I came across primaryarms.com and saw what they had, and I was very pleased that they didnt have anything on back order and everything took bout 4-5 days from when I hit submit to the upper receiver getting to my door. package was in good condition and reciever was clean and lubed and ready to shoot. of course I took it all apart just to make sure everything was their and in working condition. I will definity be recommending this website to others that need help with uppers. I do wish that they shipped threw Fedex and not UPS. Just my opinion

Spike's Tactical & Primary Arms


No need to review the Spikes Tactical Uppers. The Spikes Tactical name and the quality of their product speak for themselves! This review is about Primary Arms. I have made Primary Arms the only internet site I will deal with! I have never had even the slightest glitch with any of the many purchases I’ve made from their site. They even took the time with this purchase of two (2) Spikes Tactical uppers to personally call me and let me know the items would be shipped the following day. Primary Arms gets 10 stars in my book, and I will always be a loyal customer!

Good upper


No problems. Factory. Very Tacticool.

The Perfect Online Retailer


Not much other than that! PA had my uppers boxed and tracking numbers up in minutes!They even called to confirm that they were on the way! Great uppers as well, can't say enough good things about Spikes!

Will be my primary supplier!


Primary arms shipped extremely fast, provided the tracking number and shipped out the Monday after I placed the order (placed Saturday night). They shipped first thing in the am! I couldn't believe how quick!!! Will continue to shop!!!
